Description of Related Art

With frequent commercial activities and the rapid expansion oftransportation logistics, people are more dependent on the mobilevehicle such as car or motorcycle. At the same time, drivers are payingmore and more attention to the protection of their lives and propertywhen driving, and therefore, in addition to the performance and thecomfort of the mobile vehicle, it is also considered whether the mobilevehicle to be purchased provides sufficient safety guards or auxiliarydevices. Under this trend, in order to increase the safety of vehicles,automobile manufacturers or vehicle equipment design manufacturers havedeveloped various driving safety protection devices or auxiliarydevices, such as rearview mirrors, driving recorders, a panoramic imageinstant displaying of blind vision areas, a global positioning systemthat records the driving path at any time, and etc.

In addition, with the rapid development of digital cameras and computervisions in daily life, the digital cameras have been applied to drivingassistance systems, hoping to reduce the accident rate of trafficaccidents through the application of artificial intelligence.

Typically, during a parking process, the driver observes a conditionoutside the vehicle via rear-view mirrors on sides of the vehicle orinside of the vehicle, thereby to determine a relative position of thevehicle and a parking space so as to park the vehicle. However, thecondition outside the vehicle observed in the rearview mirrors still hasmany blind spots that cannot be seen. In addition, the front pillar, thecenter pillar, the rear pillar and other structures of the vehicle willalso block the driver's line of sight, resulting in blind spots. For theproblem of blind spots, the driver can only park the vehicle bycontrolling the vehicle based on experience, so that there are somedrivers having difficulty in parking the vehicle due to lack ofexperience, inattention, or external environmental factors (such asweather and brightness), which makes it difficult for the driver to parkthe vehicle in the parking space, and may even clash other vehicles.

The length of the contour curve of any surface of a single lens in therange of the maximum effective radius affects the surface correctionaberration and the optical path difference between the fields of view.The longer the profile curve length, the better the ability to correctthe aberration, but at the same time It will increase the difficulty inmanufacturing, so it is necessary to control the length of the profilecurve of any surface of a single lens within the maximum effectiveradius, in particular to control the profile length (ARS) and thesurface within the maximum effective radius of the surface. Theproportional relationship (ARS/TP) between the thicknesses (TP) of thelens on the optical axis. For example, the length of the contour curveof the maximum effective radius of the side surface of the first lensobject is represented by ARS11, and the thickness of the first lens onthe optical axis is TP1, and the ratio between the two is ARS11/TP1, andthe maximum effective radius of the side of the first lens image side.The length of the contour curve is represented by ARS12, and the ratiobetween it and TP1 is ARS12/TP1.

For any surface of any lens, the profile curve length within a half theentrance pupil diameter (HEP) affects the ability of the surface tocorrect aberration and differences between optical paths of light indifferent fields of view. With longer profile curve length, the abilityto correct aberration is better. However, the difficulty ofmanufacturing increases as well. Therefore, the profile curve lengthwithin a half the entrance pupil diameter (HEP) of any surface of anylens has to be controlled. The ratio between the profile curve length(ARE) within a half the entrance pupil diameter (HEP) of one surface andthe thickness (TP) of the lens, which the surface belonged to, on theoptical axis (i.e., ARE/TP) has to be particularly controlled.

The profile curve length of a half theentrance pupil diameter (HEP) of the object-side surface of the secondlens is denoted by ARE21, the thickness of the second lens on theoptical axis is TP2, and the ratio between these two parameters isARE21/TP2; the profile curve length of a half the entrance pupildiameter (HEP) of the image-side surface of the second lens is denotedby ARE22, and the ratio between ARE22 and TP2 is ARE22/TP2. For anysurface of other lenses in the optical image capturing system, the ratiobetween the profile curve length of half the entrance pupil diameter(HEP) thereof and the thickness of the lens which the surface belongedto is denoted in the same manner.

The parking auxiliary device 0040 is disposed in the movable carrier0000 and is electrically connected to the operation module 0013 of theenvironmental detecting device 0010, the state detecting device 0030,and the control device 0020. When the environmental image has theparking space 000A, the parking auxiliary device 0040 generates aprompting message based on the distance between the movable carrier 0000and the parking space 000A, the relative position of the movable carrier0000 and the parking space 000A, and the movement state of the movablecarrier 0000, so that the driver could control the control device 0020to move the movable carrier 0000 to the parking space 000A based on theprompting message. In the current embodiment, the parking auxiliarydevice 0040 generates the prompting message based on the distancebetween the movable carrier 0000 and the parking space 000A, therelative position of the movable carrier 0000 and the parking space000A, and the speed, the steering angle, the acceleration, theinclination angle, and the yaw rate of the movable carrier 0000.

The parking auxiliary device 0040 generates the prompting message whichcorresponds to a steering direction and a steering margin, andcorresponds to a gear position of the gear shift module 0022, andcorresponds to whether the driving pedal 0023 is pedaled or not, andcorresponds to whether the braking pedal 0024 is pedaled or not, so thatthe driver could control the steering wheel 0021, the gear shift module0022, the driving pedal 0023, and the braking pedal 0024 based on theprompting message to move the movable carrier 0000 to the parking space000A.

In an embodiment, the parking auxiliary device 0040 could automaticallycontrol the steering wheel 0021 to rotate, and could generates theprompting message which corresponds to the gear position of the gearshift module 0022, and corresponds to whether the driving pedal 0023 ispedaled or not, and corresponds to whether the braking pedal 0024 ispedaled or not. In this way, the driver could park the movable carrier0000 without controlling the steering wheel 0021.

In an embodiment, the parking auxiliary device 0040 could automaticallycontrol the steering wheel 0021 to rotate, and could automaticallycontrol the operations of the driving pedal 0023 and the braking pedal0024, and could generates the prompting message which corresponds to thegear position of the gear shift module 0022. In this way, all the driverhas to do during the parking process is to control the gear shift module0022 to be a forward gear or a reverse gear.

In order to increase the safety during the parking process, when theparking auxiliary device 0040 determines that a movement speed of themovable carrier 0000 measured by the speed sensor 031 of the statedetecting device 0030 is less than or equal to a starting speed, theparking auxiliary device 0040 generates the prompting message. When themovement speed of the movable carrier 0000 measured by the speed sensor031 is greater than the starting speed, the parking auxiliary device0040 does not generate the prompting message, thereby to prevent thedriver from not having sufficient time to react.

In the current embodiment, the operation module 0013 could furtherdetermine whether the environmental image has an obstruction 000Blocated between the movable carrier 0000 and the parking space 000A. Theparking auxiliary device 0040 further includes a warning module 0041,wherein when the driver controls the control device 0020 based on theprompting message and the environmental image has the obstruction 000Blocated between the movable carrier 0000 and the parking space 000A (asshown in FIG. 1D), the warning module 0041 generates a warning message.The warning module 0041 at least includes one of a voice playback member004 a, a light generating member 004 b, and an image displaying member004 c, thereby to present the warning message in forms of sounds,lights, or both of sounds and lights, or displaying an image or a text,or both of the image and the text.

In an embodiment, the parking auxiliary device 0040 at least includesthe voice playback member 004 a, wherein the warning message ispresented by playing a corresponding voice of the warning message viathe voice playback member 004 a.

In addition to determining the parking space 000A via the environmentalimage, the environmental detecting device 0010 further includes adetection wave transceiver module 0014 electrically connected to theoperation module 0013. The detection wave transceiver module 0014 sendsa detection wave in at least a direction which is not a travelingdirection of the movable carrier 0000 (e.g. a rightward direction of themovable carrier 0000), and receives a reflection detection wave of thedetection wave, wherein the detection wave could be ultrasonic wave,millimeter wave radar, lidar, infrared light, laser, or a combination ofthe foregoing. The operation module 0013 further determines whether theenvironmental image has the parking space 000A or not via the reflectiondetection wave and the environmental image, thereby to determine acorrectness of the parking space 000A via the environmental image andthe reflection detection wave.

Additionally, the detection wave transceiver module 0014 could also senda detection wave in a traveling direction of the movable carrier 0000(e.g. a frontward or a backward direction of the movable carrier 0000),and receives a reflection detection wave of the detection wave. Theoperation module 0013 determines the distance between the movablecarrier 0000 and the parking space 000A and the relative position of themovable carrier 0000 and the parking space 000A via the reflectiondetection wave and the environmental image, thereby to determine acorrectness of the distance between the movable carrier 0000 and theparking space 000A and the relative position of the movable carrier 0000and the parking space 000A via the environmental image and thereflection detection wave.

The parking auxiliary device 0040 further includes a displaying module0042 electrically connected to the environmental detecting device 0010,wherein the prompting message is displayed on the displaying module 0042as an image, a text, or both of the image and the text.

FIG. 1E is a schematic perspective view showing the displaying module0042 according to the first system embodiment of the present invention,in which the displaying module 0042 is a vehicle electronic rear-viewmirror 0100 having a display (not shown), for example. FIG. 1F is aschematic section view taken along the short side of the displayingmodule of FIG. 1E. The vehicle electronic rear-view mirror 0100 could bedisposed on a movable carrier, e.g. a vehicle, to assist in the drivingof the vehicle or to provide information about driving. Morespecifically, the vehicle electronic rear-view mirror 0100 could be aninner rear-view mirror disposed inside the vehicle or an outer rear-viewmirror disposed outside the vehicle, both of which are used to assistthe driver in understanding the location of other vehicles. However,this is not a limitation on the present invention. In addition, themovable carrier is not limited to the vehicle, and could be other typesof transportation, such as a land train, an aircraft, a water ship, etc.

The vehicle electronic rear-view mirror 0100 is assembled in a casing0110, wherein the casing 0110 has an opening (not shown). Morespecifically, the opening of the casing 0110 overlaps with a reflectivelayer 0190 of the vehicle electronic rear-view mirror 0100. In this way,external light could be transmitted to the reflective layer 0190 locatedinside the casing 0110 through the opening, so that the vehicleelectronic rear-view mirror 0100 functions as a mirror. When the driverdrives the vehicle and faces the opening, for example, the driver couldperceive the external light reflected by the vehicle electronicrear-view mirror 0100, thereby knowing the position of the rear vehicle.

Referring to FIG. 1F, the vehicle electronic rear-view mirror 0100includes a first transparent assembly 0120 and a second transparentassembly 0130, wherein the first transparent assembly 0120 faces thedriver, and the second transparent assembly 0130 is disposed on a sideaway from the driver. More specifically, the first transparent assembly0120 and the second transparent assembly 0130 are translucentsubstrates, wherein a material of the translucent substrates could beglass, for example. However, the material of the translucent substratesis not a limitation on the present invention. In other embodiments, thematerial of the translucent substrates could be plastic, quartz, PETsubstrate, or other applicable materials, wherein the PET substrate hasthe advantages of low cost, easy manufacture, and extremely thinness, inaddition to the packaging and protection effects.

In this embodiment, the first transparent assembly 0120 includes a firstincidence surface 0122 and a first exit surface 0124, wherein anincoming light image from the rear of the driver enters the firsttransparent assembly 0120 via the first incidence surface 0122, and isemitted via the first exit surface 0124. The second transparent assembly0130 includes a second incidence surface 0132 and a second exit surface0134, wherein the second incidence surface 0132 faces the first exitsurface 0124, and a gap is formed between the second incidence surface0132 and the first exit surface 0124 by an adhesive 0114. After beingemitted via the first exit surface 0124, the incoming light image entersthe second transparent assembly 0130 via the second incidence surface0132 and emitted via the second exit surface 0134.

An electro-optic medium layer 0140 is disposed in the gap between thefirst exit surface 0124 of the first transparent assembly 0120 and thesecond incidence surface 0132 of the second transparent assembly 0130.At least one transparent electrode 0150 is disposed between the firsttransparent assembly 0120 and the electro-optic medium layer 0140. Theelectro-optic medium layer 0140 is disposed between the firsttransparent assembly 0120 and at least one reflective layer 0190. Atransparent conductive layer 0160 is disposed between the firsttransparent assembly 0120 and the electro-optic medium layer 0140.Another transparent conductive layer 0160 is disposed between the secondtransparent assembly 0130 and the electro-optic medium layer 0140. Anelectrical connector 0170 is electrically connected to the transparentconductive layer 0160, and another electrical connector 0170 iselectrically connected to the transparent electrode 0150, which iselectrically connected to the electro-optic medium layer 0140 directlyor indirectly through the another transparent conductive layer 0160,thereby transmitting electrical energy to the electro-optic medium layer0140 to change a transparency of the electro-optic medium layer 0140.When a luminance of the incoming light image exceeds a certain luminance(e.g. strong light from the headlight of the rear vehicle), a glaresensor 0112 electrically connected to a control member 0180 receives thelight energy and convert it into a signal, and the control member 0180determines whether the luminance of the incoming light image exceeds apredetermined luminance, and if a glare is generated, the electricalenergy is provided to the electro-optic medium layer 0140 by theelectrical connector 0170 to generate an anti-glare performanceGenerally, if the incoming light image has a strong luminance, the glarecould be generated and thus affects the driver's line of sight, therebyendangering the driving safety.

In addition, the transparent electrode 0150 and the reflective layer0190 could respectively cover the entire surfaces of the firsttransparent assembly 0120 and the second transparent assembly 0130.However, this is not a limitation on the present invention. In thisembodiment, the transparent electrode 0150 could use a material selectedfrom metal oxides, such as indium tin oxide, indium zinc oxide, aluminumtin oxide, aluminum zinc oxide, indium antimony zinc oxide, or othersuitable oxides, or a stacked layer composed of at least two of theforegoing oxides. Moreover, the reflective layer 0190 could beconductive and made of a material selected from the group consisting ofsilver (Ag), copper (Cu), aluminum (Al), titanium (Ti), chromium (Cr),molybdenum (Mo), and an alloy thereof, or contains silicon dioxide or atransparent conductive material. However, the material of thetransparent electrode 0150 and the material of the reflective layer 0190are not limitations on the present invention. In other embodiments, thematerial of the transparent electrode 0150 and the material of thereflective layer 0190 could be other types of materials.

The electro-optic medium layer 0140 could be made of an organic materialor an inorganic material. However, this is not a limitation on thepresent invention. In the current embodiment, the electro-optic mediumlayer 0140 could be an electrochromic material. The electro-optic mediumlayer 0140 is disposed between the first transparent assembly 0120 andthe second transparent assembly 0130 and also disposed between the firsttransparent assembly 0120 and the reflective layer 0190. Morespecifically, the transparent electrode 0150 is disposed between thefirst transparent assembly 0120 and the electro-optic medium layer 0140(i.e., the electrochromic material layer). In an embodiment, thereflective layer 0190 could be disposed between the second transparentassembly 0130 and the electro-optic medium layer 0140. In addition, inthe current embodiment, the vehicle electronic rear-view mirror 0100further includes an adhesive 0114 located between the first transparentassembly 0120 and the second transparent assembly 0130 and surroundingthe electro-optic medium layer 0140. The electro-optic medium layer 0140is co-packaged by the adhesive 0114, the first transparent assembly0120, and the second transparent assembly 0130.

In the current embodiment, the transparent conductive layer 0160 isdisposed between the electro-optic medium layer 0140 and the reflectivelayer 0190. More specifically, the transparent conductive layer 0160could be used as an anti-oxidation layer of the reflective layer 0190,so that the electro-optic medium layer 0140 could be prevented fromdirect contact with the reflective layer 0190, thereby preventing thereflective layer 0190 from being corroded by the organic materials, andextending the service life of the vehicle electronic rear-view mirror0100 of the current embodiment. In addition, the electro-optic mediumlayer 0140 is co-packaged by the adhesive 0114, the transparentelectrode 0150, and the transparent conductive layer 0160. In thecurrent embodiment, the transparent conductive layer 0160 contains amaterial selected from the group consisting of indium tin oxide (ITO),indium zinc oxide (IZO), Al-doped ZnO (AZO), fluorine-doped tin oxide,and a combination thereof.

In the current embodiment, the vehicle electronic rear-view mirror 0100could be optionally provided with the electrical connector 0170. Forinstance, in an embodiment, the electrical connector 0170 could be aconducting wire or a conducting structure electrically connected to thetransparent electrode 0150 and the reflective layer 0190, so that thetransparent electrode 0150 and the reflective layer 0190 could beelectrically connected to the at least one control member 0180, whichprovides a driving signal via the conducting wire or the conductingstructure, thereby driving the electro-optic medium layer 0140.

When the electro-optic medium layer 0140 is enabled, the electro-opticmedium layer 0140 would undergo an electrochemical redox reaction andchange its energy level to be in a diming state. When external lightpasses through the opening of the casing 0110 and reaches theelectro-optic medium layer 0140, the external light would be absorbed bythe electro-optic medium layer 0140 which is in the diming state, sothat the vehicle electronic rear-view mirror 0100 is switched to ananti-glare mode. On the other hand, when the electro-optic medium layer0140 is disenabled, the electro-optic medium layer 0140 is transparent.At this time, the external light passing through the opening of thecasing 0110 passes through the electro-optic medium layer 0140 to bereflected by the reflective layer 0190, so that the vehicle electronicrear-view mirror 0100 is switched to a mirror mode.

More specifically, the first transparent assembly 0120 has the firstincidence surface 0122 which is away from the second transparentassembly 0130. For instance, external light from the rear vehiclesenters the vehicle electronic rear-view mirror 0100 via the firstincidence surface 0122, and then the vehicle electronic rear-view mirror0100 reflects the external light such that the external light leaves thevehicle electronic rear-view mirror 0100 via the first incidence surface0122. In addition, eyes of the vehicle driver could receive the externallight reflected by the vehicle electronic rear-view mirror 0100 to knowthe position of other vehicles behind. Moreover, the reflective layer0190 could have the optical property of partial transmission and partialreflection by selecting a suitable material and designing a proper filmthickness.

The display of the vehicle electronic rear-view mirror 0100 could be anLCD or an LED, and the display could be disposed inside or outside thecasing 0110, for example, on the side of the second transparent assembly0130 away from the first transparent assembly 0120, or on the secondexit surface 0134 of the second transparent assembly 0130 away from thefirst transparent assembly 0120. Since the reflective layer 0190 has theoptical property of partial transmission and partial reflection, theimage light emitted by the display could pass through the reflectivelayer 0190, thereby allowing the user to view the internal imagedisplayed by the display so as to display the warning message.

With the aforementioned movable carrier auxiliary system, a parkingauxiliary method illustrated in FIG. 1G which includes following stepscould be executed.

Step S1: the image capturing module 0011 captures an environmental imagearound the movable carrier 0000.

Step S2: the operation module 0013 receives the environmental image andanalyzes whether the environmental image has a space with a capacitygreater than a volume of the movable carrier 0000, and a length, awidth, and a height of the space is greater than a length, a width, anda height of the movable carrier; if there is the space with the capacitygreater than the volume of the movable carrier in the environmentalimage, and the length, the width, and the height of the space is greaterthan the length, the width, and the height of the movable carrier, theoperation module 0013 determines the space is the parking space 000A.

A plurality of determining ways which could be applied to the operationmodule 0013 are provided followed, so that the operation module 0013 instep S2 could determine the environmental image has the parking space000A.

(1) Referring to FIG. 1C, the operation module 0013 first determineswhether the environmental image has a parking grid marking 000C. Ifthere is the parking grid marking 000C in the environmental image, theoperation module 0013 determines whether an area within the parking gridmarking 000C has the parking space 000A or not.

(2) Referring to FIG. 1H, the operation module 0013 first analyzeswhether the environmental image has a line image forming a plurality ofcorners 000D, and selects and determines the line image with two corners000D as the parking grid marking 000C, and then determines whether anarea between the two corners 000D has the parking space 000A or not. Thetwo selected corners 000D could be adjacent corners 000D or diagonallyopposite corners 000D. The environment shown in FIG. 1C could also applythe way (2) to determine the parking space 000A with the plurality ofcorners 000D.

(3) Referring to FIG. 1H, the operation module 0013 first analyzeswhether the environmental image has a line image forming a plurality ofcorners 000D, and selects the line image with two adjacent corners 000D,and determines whether there is a line marking 000E between the twoadjacent corners 000D or not. If there is the line marking 000E betweenthe two adjacent corners 000D, the line image with two corners 000D isselected and determined as the parking grid marking 000C, and then theoperation module 0013 determines whether an area surrounded by the twoadjacent corners 000D and the line marking 000E has the parking space000A or not. The environment shown in FIG. 1C could also apply the way(3) to determine the parking space 000A with the plurality of corners000D and one of lines of the parking grid marking 000C (i.e., the linemarking 000E).

(4) Referring to FIG. 1I, the image capturing module 0011 is disposed ona backside of the movable carrier 0000 as an example for capturing anenvironmental image on a rearward of the movable carrier 0000, whereinthe backside of the movable carrier 0000 could be, for example, around atrunk of the movable carrier 0000 or on a rear bumper. The operationmodule 0013 first determines whether the environmental image has twoshunned carriers 000F. If the environmental image has the two shunnedcarriers 000F, the operation module 0013 determines whether an areabetween the two shunned carriers 000F has the parking space 000A or not.If the area between the two shunned carriers 000F has the parking space000A, the operation module 0013 determines whether one of the shunnedcarriers 000F moves or not, wherein the warning message is generatedwhen one of the shunned carriers 000F is determined moves.

An environment shown in FIG. 1J could also apply the way (4) todetermine the parking space 000A.

An environment shown in FIG. 1K which has both of the parking gridmarking 000C and the shunned carriers 000F could also apply one of theways (1) to (4) to determine the parking space 000A.

Referring to FIG. 1L, the image capturing module 0011 is disposed on afront side of the movable carrier 0000 as an example for capturing andgenerating the environmental image which is in front of the movablecarrier 0000. The front side of the movable carrier 0000 could be, forexample, a side of a head of a vehicle, a vicinity of the frontwindshield inside the vehicle, or a side of the front bumper. Anenvironment shown in FIG. 1L which has both of the parking grid marking000C and the shunned carriers 000F could also apply one of the ways (1)to (4) to determine the parking space 000A.

Step S3: the operation module 0013 determines the distance between theparking space 000A and the movable carrier 0000 and the relativeposition of the parking space 000A and the movable carrier 0000 via theenvironmental image.

Step S4: the state detecting device 0030 detects the movement state ofthe movable carrier 0000, wherein the movement state at least includesthe speed of the movable carrier 0000.

Step S5: the parking auxiliary device 0040 generates the promptingmessage by deriving based on the distance between the parking space 000Aand the movable carrier 0000 and the relative position of the parkingspace 000A and the movable carrier 0000 obtained in step S3 and themovement state obtained in step S4, thereby the driver could manipulatethe control device 0020 based on the prompting message to move themovable carrier 0000 to the parking space 000A. In the currentembodiment, when the movement speed of the movable carrier 0000 measuredby the state detecting device 0030 is less than or equal to the startingspeed, the parking auxiliary device 0040 generates the promptingmessage.

Referring to FIG. 1D, when the driver manipulates the control device0020 based on the prompting message and when there is the obstruction000B located between the movable carrier 0000 and the parking space 000Ain the environmental image, the parking auxiliary device 0040 generatesthe warning message.

The operation module 0013 detects whether an environmental image splicedby the environmental images that the four image capturing modules 0011capture has the parking space 000A. A horizontal angle of view coveredby the environmental image spliced by the environmental images that thefour image capturing modules 0011 capture is 360 degrees. Theenvironmental image spliced by the environmental images that the imagecapturing modules 0011 capture could be spliced by the operation module0013.

In an embodiment, the lenses of high Abbe number and the lenses of lowAbbe number are arranged in an interlaced arrangement that could behelpful for correction of aberration of the optical image capturingsystem.

An equation of aspheric surface is

z=ch ²/[1+[1(k+1)c ² h ²]^(0.5)]+A4h ⁴ ±A6h ⁶ +A8h ⁸ +A10h ¹⁰ +A12h ¹²+A14h ¹⁴ +A16h ¹⁶ +A18h ¹⁸ +A20h ²⁰+  (1)

where z is a depression of the aspheric surface; k is conic constant; cis reciprocal of the radius of curvature; and A4, A6, A8, A10, A12, A14,A16, A18, and A20 are high-order aspheric coefficients.

In the optical image capturing system, the lenses could be made ofplastic or glass. The plastic lenses may reduce the weight and lower thecost of the optical image capturing system, and the glass lenses maycontrol the thermal effect and enlarge the space for arrangement of therefractive power of the optical image capturing system. In addition, theopposite surfaces (object-side surface and image-side surface) of thefirst to the seventh lenses could be aspheric that could obtain morecontrol parameters to reduce aberration. The number of aspheric glasslenses could be less than the conventional spherical glass lenses, whichis helpful for reduction of the height of the optical image capturingsystem.

Furthermore, in the optical image capturing system provided by thepresent invention, when the lens has a convex surface, it means that thesurface of the lens around the optical axis is convex, and when the lenshas a concave surface, it means that the surface of the lens around theoptical axis is concave.

The optical image capturing system of the present invention could beapplied in a dynamic focusing optical image capturing system. It issuperior in the correction of aberration and high imaging quality sothat it could be allied in lots of fields.

The optical image capturing system of the present invention couldfurther include a driving module to meet different demands, wherein thedriving module could be coupled with the lenses to move the lenses. Thedriving module could be a voice coil motor (VCM), which is used to movethe lens for focusing, or could be an optical image stabilization (OIS)component, which is used to lower the possibility of having the problemof image blurring which is caused by subtle movements of the lens whileshooting.

To meet different requirements, at least one lens among the first lensto the seventh lens of the optical image capturing system of the presentinvention could be a light filter, which filters out light of wavelengthshorter than 500 nm. Such effect could be achieved by coating on atleast one surface of the lens, or by using materials capable offiltering out short waves to make the lens.

To meet different requirements, the image plane of the optical imagecapturing system in the present invention could be either flat orcurved. If the image plane is curved (e.g., a sphere with a radius ofcurvature), the incidence angle required for focusing light on the imageplane could be decreased, which is not only helpful to shorten thelength of the optical image capturing system (TTL), but also helpful toincrease the relative illuminance.

It may help to shorten the back focal length to keepsmall in size, and may reduce an incident angle of the light of anoff-axis field of view and correct the aberration of the off-axis fieldof view.

The infrared rays filter 280 is made of glass and is disposed betweenthe seventh lens 270 and the image plane 290. The infrared rays filter280 gives no contribution to the focal length of the optical imagecapturing system 20.

Third Optical Embodiment

As shown in FIG. 4A and FIG. 4B, an optical image capturing system 30 ofthe third optical embodiment of the present invention includes, along anoptical axis from an object side to an image side, a first lens 310, asecond lens 320, a third lens 330, an aperture 300, a fourth lens 340, afifth lens 350, a sixth lens 360, a seventh lens 370, an infrared raysfilter 380, an image plane 390, and an image sensor 392.

The first lens 310 has negative refractive power and is made of glass.An object-side surface 312 thereof, which faces the object side, is aconvex spherical surface, and an image-side surface 314 thereof, whichfaces the image side, is a concave spherical surface.

The second lens 320 has negative refractive power and is made of glass.An object-side surface 322 thereof, which faces the object side, is aconcave spherical surface, and an image-side surface 324 thereof, whichfaces the image side, is a convex spherical surface.

The third lens 330 has positive refractive power and is made of plastic.An object-side surface 332 thereof, which faces the object side, is aconvex aspheric surface, and an image-side surface 334 thereof, whichfaces the image side, is a convex aspheric surface. The image-sidesurface 334 has an inflection point.

The fourth lens 340 has negative refractive power and is made ofplastic. An object-side surface 342, which faces the object side, is aconcave aspheric surface, and an image-side surface 344, which faces theimage side, is a concave aspheric surface. The image-side surface 344has an inflection point.

The fifth lens 350 has positive refractive power and is made of plastic.An object-side surface 352, which faces the object side, is a convexaspheric surface, and an image-side surface 354, which faces the imageside, is a convex aspheric surface.

The sixth lens 360 has negative refractive power and is made of plastic.An object-side surface 362, which faces the object side, is a convexaspheric surface, and an image-side surface 364, which faces the imageside, is a concave aspheric surface. The object-side surface 362 has aninflection point, and the image-side surface 364 has an inflectionpoint. It may help to shorten the back focal length to keep small insize. Whereby, the incident angle of each view field entering the sixthlens 360 could be effectively adjusted to improve aberration.

The infrared rays filter 380 is made of glass and is disposed betweenthe sixth lens 360 and the image plane 390. The infrared rays filter 390gives no contribution to the focal length of the optical image capturingsystem 30.
